How long does the battery last, and how do you know when it needs to be replaced?

Average battery life is 6 months. We recommend Duracell batteries as replacements mostly due to size inconsistencies between battery manufacturers. Do not leave your bass plugged in when you have finished playing, as this will drain your battery faster. Battery life of course depends on how often and how long you play. When the sound of your bass becomes distorted, it's ready for a new battery.
